Body text sample
Stronger contrast
Thin fonts and imagery behind text make effective contrast worse in practice, especially on phones.
Where this comes from on Shopify
Theme settings, custom CSS for badges and countdowns, and app-injected sale strips.
What this issue means
What this issue is
Automated tools compare foreground and background colors to thresholds (often 4.5:1 for normal text under WCAG AA). Thin fonts and images behind text complicate measurement.
Why it matters
Contrast affects readability for many users, not only those with diagnosed vision disabilities. Marketing palettes sometimes prioritize brand over legibility.
Fixes
Darken text, lighten background, or add a solid backdrop behind text on busy images. Re-check hover and disabled states.
How to fix on Shopify
Sale badges and countdowns are frequent offenders in custom CSS.
How to fix
Increase contrast to at least 4.5:1 for normal text (AA). Test hover, disabled, and error states.
Add a solid scrim behind text on photos instead of relying on busy backgrounds.
Common mistakes on Shopify
- Custom CSS on `.btn` that breaks sale badges.
- White text on variable photo backgrounds.
- Editing checkout (limited) vs theme—know which surface you can change.
- Forgetting to test accelerated/mobile themes.
How to verify the fix
- Preview the theme or use a development theme URL the scanner can reach.
- Test cart and collection templates if that is where the issue appeared.
- Rerun the scan after theme deploy; keep before/after report URLs.
